Chapter 3 · The Yoga of Action · Krishna said
Bhagavad Gita 3.22 — Krishna also works
न मे पार्थास्ति कर्तव्यं त्रिषु लोकेषु किञ्चन। नानवाप्तमवाप्तव्यं वर्त एव च कर्मणि ॥
na me pārthāsti kartavyaṃ triṣu lokeṣu kiñcana | nānavāptamavāptavyaṃ varta eva ca karmaṇi ||
Meaning
Partha, there is no duty for me to do in all the three worlds, nothing I lack or need to gain — and yet I keep working.
